Definitions

  • the invention relates to an exhaust gas turbocharger.
  • An exhaust gas turbocharger or turbocharger for short, is a supercharging system for an internal combustion engine by means of which the cylinders of the internal combustion engine are exposed to an increased supercharging pressure.
  • a turbocharger consists of an exhaust gas turbine in the exhaust gas stream (downstream path) which is connected via a common shaft to a compressor in the induction tract (upstream path). The turbine is set into rotation by the exhaust gas stream from the engine and thereby drives the compressor.
  • the compressor increases the pressure in the induction tract of the engine such that as a result of said compression a greater volume of air is drawn into the cylinders of the internal combustion engine during the induction stroke than in the case of a conventional naturally-aspirated engine. More oxygen is available for combustion as a result.
  • the torque and the power delivery are increased appreciably due to the increasing mean effective pressure of the engine.
  • Supplying a greater volume of fresh air combined with the inlet-side compression process is called supercharging. Since the energy for supercharging is taken from the fast flowing, very hot exhaust gases by the turbine, the overall efficiency of the internal combustion engine is increased.
  • EGTs High demands are placed on the EGTs. This is primarily due to the high exhaust gas temperatures of in excess of 1000° C. and the totally different gas volumes, which vary according to rotational speed range, and the high maximum rotational speeds of up to 400,000 revolutions per minute.
  • Conventional EGTs are composed inter alia of a turbine housing and a compressor housing, both of which are fixed to a bearing housing.
  • the bearing housing has a flange on the turbine side and a flange on the compressor side, with the turbine housing being connected to the turbine-side flange with the aid of securing means, preferably by means of bolts.
  • the bearing housing largely remains in the normal temperature range, in particular also owing to the air cooling from the compressor side.
  • an extremely time-variable and in part also very high temperature gradient is established in particular along the bolts from the turbine housing to the bearing housing.
  • the bolts In order for the bolts to be able to apply the necessary high tensile stress to the turbine housing, they must be sufficiently pretensioned to join the turbine housing to the bearing housing in a force-fitting and form-fitting manner over the entire operating temperature range.
  • the concept underlying the present invention consists in securing the turbine housing with the aid of a securing means which applies the tensile stress from the compressor-side flange of the bearing housing.
  • a further advantage in the use of the inventive securing means lies in the fact that a method for automatic assembly of turbochargers is provided in which the bolt head is freely accessible for the first time.
  • the turbine housing can be manufactured considerably more easily and more cost-effectively.
  • the compressor-side flange of the bearing housing has a molding for receiving the securing means.
  • the securing means is embodied as a bolt acting as a tie rod.
  • the length of the thread of the bolt is not longer than the thickness of the turbine housing, it also being advantageous that in the area of the thread the bolt has a greater diameter than the shaft diameter. As a result a greater material cross-section is available for absorbing the tensile force in the high temperature load range.
  • the thread of the bolt is embodied as a self-sealing thread.
  • the securing means in particular bolt, has a head with internal engagement, a hexagon socket for example.
  • FIG. 1 is a schematic representation of an inventive fixing of a turbine housing
  • FIG. 2 a shows a schematic layout of an exhaust gas turbocharger having a turbine housing fixing according to the prior art
  • FIG. 2 b is a schematic detailed representation of the fixing of a turbine housing.
  • FIG. 2 a shows a layout of an exhaust gas turbocharger 102 according to the prior art, comprising a turbine 118 and a compressor 116 .
  • a turbine wheel 108 is rotatably mounted inside a turbine housing 106 of the exhaust gas turbine 118 and connected to one end of a shaft 110 .
  • a compressor wheel 104 is likewise rotatably mounted inside the compressor housing 100 of the compressor 116 and connected to the other end of the shaft 110 .
  • Hot exhaust gas from a combustion engine (not shown here) is admitted via a turbine inlet 112 into the turbine 118 , as a result of which the turbine wheel 118 is set into rotation.
  • the exhaust gas stream exits the turbine 118 through a turbine outlet 114 .
  • the turbine 118 drives the compressor 116 via the shaft 110 which couples the turbine wheel 108 to the compressor wheel 104 .
  • the turbine housing 106 is secured by means of a bolt 107 to the turbine-side flange 123 of the bearing housing 124 .
  • the compressor housing 100 is secured to the compressor-side flange 122 of the bearing housing 124 .
  • FIG. 2 b shows a schematic detailed representation of an exhaust gas turbocharger according to the prior art.
  • the turbine housing 106 is secured to the turbine-side flange 123 of the bearing housing 124 by means of a short bolt 107 . Since for constructional reasons the diameter of the bearing housing 124 between the compressor-side flange 122 and the turbine-side flange 123 is substantially smaller and the bearing housing has a recess 125 for receiving the head of the bolt, the threaded connection of the turbine housing must be introduced and screwed in manually in a time-intensive manner.
  • FIG. 1 shows a schematic representation of an inventive fixing of a turbine housing 106 to a bearing housing 124 .
  • the turbine housing 106 which is mounted in a form-fitting manner to the turbine-side flange 123 of the bearing housing 124 , encloses a turbine wheel 108 disposed on a shaft 120 .
  • the force fit between turbine housing 106 and bearing housing 124 is created by means of a long bolt 130 which is inserted through a recess of the compressor-side flange 122 .
  • the long bolt 130 embodied as a tie rod, is pretensioned in order to secure the turbine housing 106 reliably to the bearing housing 124 even at high exhaust gas temperatures.
  • the bolt 130 has a threaded section 132 which is preferably turned in completely into the turbine housing 106 . Tests conducted by the applicant have shown that it is also advantageous if the compressor-side flange 122 has a recess for receiving the bolt head 133 of the bolt 130 . A disruptive swirling of the air mixture that is to be compressed on the compressor side is reduced thereby. It is also conceivable to use other types of fixing than screwed connections, such as, for example, stud bolts or plug-and-socket connections using rivets, or locking rings.
  • An advantage of the inventive fixing is that the bolts have a long length as a result of the threaded connection of the turbine housing to the compressor-side flange and the temperature difference can be distributed over a substantially greater length.
  • the average temperature of the threaded tie rod connection is less than in the case of a short bolt according to the prior art.
  • a further advantage is that the effect of a different thermal coefficient of expansion of the material of the turbine housing and of the material of the bolts, which is the cause of a drastic reduction in, extending as far as total dispersion of, the pretensioning force in the case of short bolt lengths, is greatly diminished owing to the greater expansion lengths.
  • the reliability of the threaded connection is increased.
  • turbochargers no longer have to be manually introduced and tightened between the compressor-side and turbine-side flanges during the manufacture of the turbocharger.
  • reliability is further increased as a result of the automated threaded connection, since the pretensioning force can be preset on automated production equipment.
  • Tests conducted by the applicant have shown that totally automated high-volume production of turbochargers is made possible by means of the inventive embodiment.
  • the balanced bearing housing which has rotor and mounting can be installed in the turbine housing, which is preferably clamped vertically at the assembly station, with the compressor side upward. Following this, both are bolted together with the aid of the securing means, likewise supplied from above, preferably bolts embodied as tie rods. The compressor housing is subsequently mounted and secured.
